Engineering Selection Recommendations

The OSTYK42106030 serves as a direct functional equivalent to the 4DB-W108-06 for applications requiring a 6-circuit barrier block connector with 0.325" pitch and screw termination.

Compliance and Certification Basis:

  • Both components maintain UL94 V-0 flammability rating, ensuring equivalent safety performance in insulation materials
  • Both components are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions
  • The OSTYK42106030 is an active product with established supply chain availability, whereas the 4DB-W108-06 is obsolete

Electrical Performance:

  • The OSTYK42106030 provides a higher voltage rating (300V vs. 150V), offering enhanced margin for applications operating at or below 150V
  • Current rating remains constant at 20A across both components
  • Wire gauge acceptance (12-22 AWG) is identical

Mechanical and Thermal Considerations:

  • Pitch, circuit count, and mounting configuration are identical
  • The OSTYK42106030 provides extended operating temperature range (-40°C to 105°C), accommodating broader environmental conditions
  • Bottom termination differs (PC pin vs. wire wrap); PCB mounting applications require verification of hole pattern compatibility

The OSTYK42106030 is suitable for direct substitution in new designs and replacement applications where the 4DB-W108-06 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the OSTYK42106030 replace the 4DB-W108-06 in existing applications?

A: The OSTYK42106030 is functionally equivalent for applications requiring a 6-circuit barrier block with 0.325" pitch and screw termination. The primary consideration is bottom termination compatibility: the 4DB-W108-06 uses wire wrap termination, while the OSTYK42106030 uses PC pins. Verify that the PCB hole pattern and mounting method accommodate the PC pin configuration.

Q: What are the key differences between these two components?

A: The components are equivalent in circuit count, pitch, current rating, wire gauge, and flammability rating. Differences include: voltage rating (150V vs. 300V), bottom termination method (wire wrap vs. PC pin), terminal screw finish (zinc vs. nickel), insulation material (thermoplastic vs. polyamide), and operating temperature range (105°C vs. -40°C to 105°C). The OSTYK42106030 provides enhanced electrical and thermal specifications.

Q: Are both components RoHS compliant?

A: Yes. Both the 4DB-W108-06 and OSTYK42106030 are ROHS3 compliant and meet current regulatory requirements for hazardous substance restrictions.

Q: What is the significance of the different bottom termination types?

A: The 4DB-W108-06 features wire wrap termination, suitable for wire-to-board connections using wire wrapping techniques. The OSTYK42106030 features PC pin termination, designed for direct insertion into PCB holes. Selection depends on the application's connection method and PCB design.

Q: Is the OSTYK42106030 available in the same packaging as the 4DB-W108-06?

A: The OSTYK42106030 is supplied in bulk packaging, whereas the 4DB-W108-06 packaging specification was not provided. Verify packaging requirements for your procurement process.

Q: Can the higher voltage rating of the OSTYK42106030 cause compatibility issues?

A: No. A higher voltage rating indicates enhanced electrical capability and does not create compatibility issues for applications operating at or below the original 150V specification. The component is suitable for use in circuits rated at 150V or lower.
